Jolyn: thanks for info. I used to mash for #1, cos didn't have effective blender cum steamer then; last week when I prepared for bb G, I used the blender, texture looks ok leh, enough moisture and just before I served, I added ebm. So far bb G is ok, poo is normal. Because, now I'm testing out, I didn't let him eat many times in a row, so maybe that's why nothing happen. Anyway, thanks, shall monitor. Also for your info, potato can be shelved till when they are 8 or 9 months. They need more nutritious stuffs more than the carbo from potato.
